Module etag 

Entity tags and the If-Match / If-None-Match conditions (RFC 9110 sections 8.8.3 and 13.1).

Examples

use parse_net::{self as pn, EntityTag};

let v2 = EntityTag::strong(b"v2")?;
assert!(pn::if_none_match(b"\"v1\", W/\"v2\"", &v2)?);         // weak comparison: 304
assert!(!pn::if_match(b"W/\"v2\"", Some(&v2))?);               // strong comparison: 412
assert!(pn::if_match(b"*", Some(&v2))? && !pn::if_match(b"*", None)?);
